ZF 2099.110.042 P.T.O. SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2099.110.042 P.T.O. SHAFT is a critical power take-off shaft engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part transfers rotational energy from the transmission gear train to auxiliary hydraulic pumps or driven equipment, ensuring seamless power distribution in heavy-duty industrial applications. The SKU 2099.110.042 sits within the output shaft assembly, directly engaging with the differential gear set to deliver reliable torque under high-stress conditions. Precision-machined from forged alloy steel, this shaft maintains exacting tolerances to minimize vibration and wear, extending the service life of your ZF drivetrain.

Symptoms of Failure

• Oil leaks near the PTO housing: A worn 2099.110.042 shaft can develop surface scoring, breaking the seal between the shaft and housing, leading to transmission fluid seepage.
• Gear slipping under load: When the P.T.O. shaft splines wear down, the connection to the driven component becomes loose, causing intermittent power loss or complete disengagement during operation.
• Abnormal grinding or whining noises: Bearing surface degradation on the shaft produces metallic chatter or high-pitched sounds, especially when engaging the PTO system.
• Vibration through the chassis: An unbalanced or bent shaft transmits harmonic vibrations into the transmission case, noticeable at specific RPM ranges.

Technical Specifications

Compatibility

This P.T.O. shaft is specifically designed for ZF WG100, WG130, and WG131 transmissions. It also fits select WG180 and WG200 series models when used with the correct DIFFERENTIAL HOUSING adapter. The shaft interfaces directly with the DIFFERENTIAL assembly (part 2099109002) and the CROWN WHEEL (part 2099364014) to distribute torque. For complete drivetrain rebuilds, pair this shaft with the DIFFERENTIAL unit (part 2099209001) to ensure proper gear mesh alignment.
